[V3dot10] SqueakLight|II #7068 - You may not create any more undefined objects--use nil

[Klaus D. Witzel]

Hi list,

don't know if the v3dot10 list is still okay for SqueakLight feedback but,  
here goes:

o downloaded a fresh copy from www.squeak.org
o started the .image and made flaps go away
o launched the Preferences browser and typed 'scroll'
o got this (otherwise) wonderful message

Will continue trying to use SqueakLight for developer activities and  
report what I find.

/Klaus
